PLOW.

Application filed September 8, 1913.

T all whom it may concern:

Be it known that we, FRANK E. DAVIs and WILLIAM WV. CAMERON, both residents of La Crosse, in the county of La Crosse'. and State of Wisconsin, have invented new and useful Improvements in Flows, of which the following is a full, clear, and exact description.

The invention relates to plows and more particularly to devices for pivotally connecting the plow-carrying beam to the tractor or supporting frame.

The invention designs to provide an improved adjustable coupling for the plow beam which permits the plow beam to be adjiisted laterally and effect proper spacing between the plows of a gang.

The invention further designs to provide improved coupling means for the plow beam which permits the plow body to be angled laterally or leveled.

The invention further designs to provide an improved pivotal connection between the plow beam and the coupling whereby it is connected to the frame.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Figure 1 is a plan of a portion of a tractor plow embodying the invention. Fig. 2 is an enlarged plan of the improved coupling for the beam. Fig. 3 is a section taken on line 33 of Fig. 2.. Fig. *1 is a section on line H of Fig. 2. Fig. 5 is a section taken on line 55 of Fig. 2. Fig. 6 is a section taken on line 66 of Fig. 2, the spacing bar between the beam members being shown in elevation. Fig. 7 is a section taken on line 77 of Fig. 5. Fig. 8 is a detail, vertical, transverse section showing one side of the pivotal connection between the beam and the coupling. Fig. 9 is a detail view of the adjusting collar. Fig. 10 is a detail view of the spacing bar between the members of the plow beam. Fig. 11 is a section on line 1111 of Fig. 10.

The tractor frame'comprises a diagonal bar 5 which is made of angle iron and comprises a vertical flange 6 and a top flange 7. The several couplings for the plows, respectively, are each secured to this diagonal bar in properly spaced relation, as well under= stood in the art, and the diagonal bar is secured to the front rail 5 of the frame by Specification of Letters Patent.

suitable means including a longitudinal I bar 5 are usually formed of Wrought metal .and are suitably spaced apart by a block 5 1 so their front ends will embrace, or be disposed at the sides of, the coupling whereby the beam is pivotally connected to the frame.

The coupling between the front end of the plow beam and the frame bar 5 comprises a bracket 12 which has a horizontal portion 12 which fits on the top of bar 5, and a downwardly extending portion 13 fitting against the side of flange 6 of said bar. Bracket 12 is rigidly secured to bar 5 bybolts 14 which extend through portion 13 of the bracket and through the flange 6 of the diagonal frame bar. constitutes one member of a two-part coupling for the beam, and provides means on the frame to which the other member 15 of the coupling may be secured to the frame. Coupling member 15 comprises a flat portion 16 which fits on the top of bracket 12 and is provided with a tapered socket 17 which fits around a correspondingly shaped projecting lug 18 on the top of bracket 12 to pivotally connect member 15 and bracket 12, and to pivotallyconnect the members of the coupling. This pivotal connection is provided between the coupling members 12, 15 to permit the plow beams to be adjusted laterally to properly space them from one another or to give the landside the correct angle with respect to the draft. A bolt 19 extends through lug 18 of bracket 12, member 15 and the top flange of bar 5 to hold the member 15 on bracket 12. The pivotal connection between member 15 and bracket 12 is centrally disposed and a draw-bolt 20 is provided at each side of said pivot so that, by loosening one and tightening the other, coupling member 15 may be accurately adjusted to correspondingly adjust the beam. At each side, bracket 12 is provided with a perforated lug 21 and member 15 is provided with a perforated lug 22 for the bolts 20, respectively.

At each side of the pivotal connection between bracket 12 and coupling member 15 a bolt 23 extends through the top flange of bar 5, the top of bracket 12 and through a slot 2-1 in member 15. These bolts 23 serve This bracket lac connection between the members thereof provide for adjustment and firm securement between the coupling and the frame bar.

The pivotal connection between the front end of the beam and the coupling comprises a pin or bolt 2'? which is held in-a bearing member 28 which is adjustably connected to the coupling member 15. The rear end of the latter is formed into a housing 29 having an opening 30 extending transversely therethrough. Bearing member 28 fits. snugly between the front and rear walls of housing 29 and carries the pivot pin 2? to which the plow beam is connected to swing vertically, so it can be raised out of, or lowered into, the soil. In practice, lateral adjustment of the plow beam is desirable to give the proper angle to or to level the plow body transversely, and for this purpose an adjustable connection is provided whereby the plow beam, pin 21. and bearing 28 may be angularly and vertically adjusted. This adjustable connection v comprises a lug 32 centrally disposed on the top of bearing member 28 which fits into a seat 33 in the top wall of housing 29, the lug and seat being formed to permit member 28 to move pivotally in the housing, and drawbolts 34, one at each side of said pivotal connection. Each of these draw-bolts has a head 35 which is countersunk in the bottom of member 28, extends upwardly through said member, and through the top wall of housing 29. By releasing the nut 36 at the upper end of one of these drawbolts 3%, and taking up the other, the bearing member may be adjusted into the desired angular position to properly level or angle the plow-body. Bolts-37 have heads which are countersunk in the front of bearing member 28, extend rearwardly through said members and through arcuate slots 40 in the rear wall of housing 29 and nuts 39 on said bolts are adapted to firmly clamp and lock the bearing member 28 in its assigned position in coupling member 15. This connection between the bearing member and the coupling provides means where by the angle of the plow body may be readily varied to a nicety and whereby the bearing will be firmly secured to the coupling.

In practice, it is desirable to avoid lost motion at the pivotal connection about which the beam swings vertically, and one feature of the invention consists in providing means for this purpose. At each end of pin 27 a bearing-sleeve 12 is provided and this sleeve has a conoidal bearing surface 43 which fits in a correspondingly tapered. opening 44: in the beam members 52, 53, respectively.

Bearing member 28 fits between the front ends of beam members 52, 53, to space them. apart and nuts l5 at the ends of pin 27 are adapted to clamp bearing sleeves 4:3 to member 28, a washer 4-6 being interposed between each nut 45 and sleeve 42. To provide for the adjustment of the bearing sleeves so that their bearing surfaces will fit snugly in the beam members, and to prevent the nuts from clamping the sleeves so that binding be tween the sleeves and the beam memben. will result, each end of bearing member 28 is provided with plural series of recesses 18, 19 and. 50 of different depths, each series of recesses being adapted to receive a series of teeth or lugs 51 on the inner end of one of the bearing sleeves 42. By setting collar 12 so that its teeth 51 will pass into that series of notches in bearing member 28 which will cause sleeves 42 to be spaced so that the conical bearing surfaces in members 52, 53 will fit snugly around said sleeves, lost motion between the beam and its pivot will be effectively eliminated. If the bearing surfaces become worn, thesleeves, upon release of clamp nuts 45, may be turned to bring their teeth into a deeper series of notches in bearing member 28 to compensate for the wear. This connection between the beam and its pivot thus provides one which permits the lateral angle of the plow body to. be effectively maintained and which overcomes lost motion at the pivotal connection for the beam.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.
